Dynamic Response of Model Footing on Reinforced Sand
The free vibration tests were conducted on model footing resting on unreinforced and reinforced. The sand was reinforced with the human hair fibers and geogrids (PET and HDPE). The fiber inclusion was considered as 0.5% by dry weight of sand. The sand bed was filled in 8 layers, and each layer was compacted using a calibrated plate vibrator to achieve the desired relative density (80%). The free vibration tests were conducted in model test tank by varying the depth of reinforcement (dr) by keeping the width of reinforcement (wr) as constant. The results indicate that the hair fiber reinforcement and geogrid reinforcement could improve the natural frequency of the soil-foundation system. Damping is found to reduce with the inclusion of both reinforcing materials.
